These can be done by hand on a drawing board, but I prefer a computer. However, sketches like these are a good way to prepare for a 3D CAD model.įor more complicated objects or drawings other people will work from, I do ‘proper’ technical drawings. It’s a memory aid rather than a technical drawing. A rough drawing capturing the shape and dimensions needed to make the item is good enough.
It’s the key used on my lathe’s 4-way tool-post.įor objects this simple, I’d do a ‘back of an envelope’ sketch. I’m not competing with the Alibre thread! The idea is to get people started by demonstrating how straightforward it can be to 3D model simple objects without plunging into shark-infested depths. The ‘starter’ piece got some positive feedback and a PM conversation about finding up-to-date FreeCAD Tutorials with Thor inspired me to show what happens once FreeCAD is ready to go. I find it handy for simple work, and as a safety-net in the event Fusion360 becomes unaffordium. FreeCAD is of interest because it’s Open-Source free, not because it’s the best possible CAD choice.
As getting started with 3D-CAD is a problem I recently outlined how to get FreeCAD into a position where a beginner could start modelling.
